Hi there, @tedhayden1949.
Welcome to the Community. At the moment, Job costing feature is only available in QuickBooks Online.
I can see the importance of this functionality in your self-employment business, tedhayden1949. I'm taking note of your needs and share this with our developers while we're still looking for ways to enhance our product and services to everyone.
Please note that all our suggested plans are subject for a thorough inspection to make sure they're fully functional when they decide to add them to QB Self-employed.
In the meantime, I'm inviting you to frequently visit the QBSE blog site to get updated news of product enhancements.
Just in case you decide to shift from QBSE to QB Online, check out this help article: Switch from QuickBooks Self-Employed to QuickBooks Online. It helps you learn everything about moving your data files over to QBO.
Feel free to visit again should you need more help. We're always here to guide you.
